PNEUMATIC CASH-CARRIER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 583,246, dated May 25,1897'; Application filed July 29, 1895. Serial No. 557,447. (No model.)

To aZZ whom it may concern:

Be it known that I, LOUIS G. BosTEDo, of Chicago, Illinois, haveinvented certain new and useful Improvements in Pneumatic Gash- CarrierApparatus, of which the following is a specification.

This invention relates to a back-stop for arresting a carrier passingthrough the main tube of a pneumatic cash-carrier system-while a carrieris being delivered into the main tube through a branch tube, as, forexample, at a salesmans station.

The drawing is a broken elevation showing a section of the maindespatoh-tube, the switch-box, branch tube, and stop, two positions ofthe latter being shown.

In the drawing, A represents the main despatch-tube, which is providedat intervals with apertures a to receive carriers. Fitted over suchapertures is the base B of a branch despatch-tube O. The upper end ofthe latter is covered by a hinged flap or cover D, and the movements ofsaid flap control a backstop E, the end of which, as shown, protrudesthrough an aperture in the wall of the main tube A and is pivoted withinthe box B to a rocking arm F, mounted on the tube A. A spring Gsurrounds the stop and normally tends to withdraw its end from the tubeA. A flexible connector II has one end attached, preferably, adj ustablyto lever F and is conducted through the tube 0, and has its other endmade fast to a lug cl on" the flap D. The connector II is preferably inthe form of a thin steel tape, which, lying flat against the wall of thetube, does not interfere with the carrier.

In the operation of the device when the salesman wishes to despatch acarrier through the branch tube 0 he first opens the flap D, and therebymoves the back-stop E into position to intercept the carrier movingthrough the main tube toward the station. When the carrier is insertedin the branch tube, it is almost instantly drawn through it and into themain tube, and the flap may be allowed to close, as it will by reason ofthe suction in the branch tube. The movement of the flap and theback-stop will not be so rapid as the movement of the carrier throughthe branch,

and therefore such carrier despatched through the branch tube will beout of the way before the intercepted carrier will be released by theupward movement of the back-stop.

It will be observed that the back-stop, its spring, lever, and the lowerend of the operating-cord are all within the air-tight base B, and thatthe operating-tape extends through the branch tube 0. This constructionand arrangement are important,because wherever the main dispatch-tube isperforated it should be covered by some air-tight closuresuch,

for example, as the base Band by carrying the operatin g-tape H upthrough the despatchtube it can be connected to the under side of theflap D and kept out of the way, as well as included in the area which issubject to the exhaust. The operation of this back-stop device does notnecessitate the opening of the main tube or any of its connections tothe atmosphere. Of course the form of the base 13 and of thedespatch-tube, as well as the specific arrangement of the back-stop withits operating lever and spring, may be varied.

I have shown and described the back-stop as passing through the wall ofthe tube A, but obviously the tube A may be cut away back to the wall ofthe base B, and in such case the back-stop would be supported, say, fromthe wall of said base and simply project into the path of the carrierwithout passing through the wall of the main tube.

I claim- 1. In a pneumatic carrier system the combination with a maindespatch-tube of a branch delivering thereto, said branch having areceiving-aperture, a movable cover for said aperture, a movableback-stop adapted to be projected into the path of a carrier passingthrough the main tube, a connector between said movable cover an d theback-stop whereby when the cover is moved to open the aperture theback-stop is moved through the connector into position to intercept thecarrier passing through the main tube toward the branch and a springnormally acting to withdraw the back-stop from the path of the carrierand to hold the cover in a closed position, substantially as described.

2. The combination with a main despatchtube, of a branch deliveringthereto and havtube and connected to the flap, substantially in g abox-like enlargementinclosing the juncas described. tion, aspring-actuated back-stop projecting t w m through an aperture in thewall of the tube, LOUIb bOSlEDO' 5 a pivoted lever on which theback-stop is Witnesses:
